I think Shed nailed it, whenever certain posters deny the wider benefits of LHR to the UK, the word "grievance" was used.
That sums up the mentality, it's prevelant back home in Scotland where people are constanatly angry at not being served their "fair share" on a plate in their own locality. MAN is doing rather well without trying to constrain LHR, as is LGW. We need to see LHR the same way Changi is seen in Singapore, KUL in Malaysia etc, a proper staregic national asset. Too much to ask where all politics is local of course.
